Brussels S Train
It will offer fast connections and increased frequency within a 30 km (19 mi) radius of the region, covering a territory inhabited by 2.5 million people.The scope includes widening existing railway lines from double to quadruple; a few additions like the Schuman-Josaphat tunnel; the creation or re-activation of stations just outside Brussels' city centre (Germoir/Mouterij and Arcades/Arcaden on the south-east, Brussels-West and Tour et Taxis/Thurn en Taxis on the west); and the acquisition of new rolling stock.Construction requires the approval and funding from the Federal Government and the three regions, as well as the collaboration of four public transit companies (NMBS/SNCB, MIVB/STIB, De Lijn and TEC).However, Belgium's administrative complexity caused numerous delays and postponements; the network will now be put into service between 2015 and 2025.Increased frequencies and passengers, however, requires other significant infrastructure projects, in addition to the Schuman-Josaphat tunnel: As of 2020, most services are operated by either new Siemens Desiro or refurbished MS86 "Sprinter", both electric multiple units.
